SUPERVISOR RESPONSIBILITIES
7.1.
CALIBRATION
Calibration settings of walk-through metal detectors are dependent upon individual
security screening requirements and, therefore,
must be the responsibility of the
screening installation
. Program and Sensitivity settings should be established at a
level that permits the detector to detect all forbidden objects that can be reasonably
expected to appear at a particular screening station. Actual forbidden objects should be
used as targets for initial calibration.
An Operational Test Piece (OTP) is an object similar in size, shape and composition to
the smallest forbidden target. Once the walk-through metal detector is properly calibrat-
ed, an OTP may be used to simulate the forbidden objects and verify calibration on a
regular basis. The OTP thereby offers a generally accepted means of verifying calibra-
tion without the necessity of having on hand actual weapons at the screening station on
a daily basis.
7.2.
FAA TEST PIECE
Garrett manufactures an OTP made to the specifications of the U. S. Federal Aviation
Administration (Garrett Accessory #1600600).
It is important to understand that OTPs come in various sizes, shapes and composi-
tions, depending upon the calibration requirements of individual screening installations.
The FAA OTP is similar to ones used for regular testing of the detection capability of
metal detectors in United States airports.If the requirements for your Magnascanner
vary from FAA requirements, different test piece(s) should be considered.
Types of Audio Alarms
Understanding the audio alarms the CS 5000 can sound will enable both supervisors and opera-
tors to understand the detector better and help assure totally accurate screening. Each of three
unique audio alarms is designed to call the operator s attention to current circumstances:
1. Set-up Alarm:
Produces two short beeps as a person is walking through the unit. This
alarm indicates that the metal detector is in a set-up mode and is not ready for operation.
Wait for green

light (press

touchpad, if necessary). Person(s) who trig-
gered the Set-up Alarm must pass through the unit again.
2. Standard Alarm:
Occurs when red
ALARM
light appears and a targeted amount of metal
is detected according to Program and Sensitivity levels.
3. Warble Alarm:
Occurs when a large metal mass, such as a wheelchair, furniture or large
metal container is moved through or near the Magnascanner. The large amount of metal has
saturated the detector s receiver circuits and the warble alarm is an indicator that the opera-
tor should correct the situation before allowing anyone to pass through the metal detector.
